I'm swapping an LT1 out of a 95 z28 into my car. The engine came from the junkyard, so now all the hoses are disconnected or cut. I noticed the opti has a couple of vaccuum lines coming out of it and I know the 95 is a vented opti. Where do these lines go? One appears to T off of the other. A friend told me one runs into the intake elbow, but I don't have an intake elbow. Can I just run the line into a vaccuum manifold port?

 

One runs to the driver's side of the intake and the other to the intake elbow.

 

Here is where the opti gets vacuum.

The vacuum line must have these items on it.

This is how they connect at the opti. The hose that goes to the intake elbow is for filtered air (not vacuum). You will need to find a way to connect that somewhere on your setup and it should be after the MAF.

 

thanks a ton, thats exactly what i needed
